The Importance Of Air Pressure In A Soccer Ball

686 Words3 Pages

My project deals with adjusting the air pressure in a soccer ball, and seeing how far it travels when the same force is applied with varying measurements of air. I am testing this topic to show the pros and cons of having a soccer ball correctly and incorrectly pumped while using it to practice and during games. With my project idea there would have been to many variables while testing, I would have to worry about the amount of pressure and how hard I would have to kick the ball. However, I fixed that with adjusting one of the variables... While kicking a soccer ball it is nearly impossible to kick with the same speed, strength, and accuracy, every time; so I will be making a pendulum like contraption to hit the ball with the same amount …show more content…

Air pressure, more commonly known as atmospheric pressure, is an important unit of measurement when dealing with my project. Atmospheric pressure, means the force per area unit pushed against a surface by the weight of the air above that surface. The atmospheric pressure is caused by the weight of the air from a certain measurement point. I will have to use measurements specific to air pressure like bar, psi, and lbs; to measure the amount of air I have pumped into the soccer ball and record it. Atmospheric pressure is a super important part of my project and need the measurements to carry it out. Going by FIFA’s requirements the normal air pressure of a soccer ball should be between 8.5-15.6psi (per square inch) or 0.6-0.8bar . Some soccer balls indicate pressure in bar units, others in psi and lbs. I will be using a size 5 soccer ball to carry out my testing since that is the size I use and the what the professionals use. In this experiment I will be changing the amounts of air, by adding more or less, and see how it affects the distance the ball travels. I will also use the same soccer ball each time so I do not have to many manipulated variables. Which leads me to my next

Summary of “Forces on a baseball” by NASA.gov The article, “Forces on a baseball,” by NASA.gov, presents the facts on what makes a baseball fly threw the air a baseball. NASA.gov presents readers with the facts and breakdown drag,lift and weight, while explaining the air and temperature can affect how high and far the ball goes. The article references Newton’s first law of motion, “According to Newton's first law of motion, a moving baseball will keep moving in a straight line unless it is affected by another force.” As the article concludes, the author highlights that if the ball is perfectly round and smooth, its center of pressure will be exactly in the middle point.

In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.

The book, Out of My Mind, by Sharon Draper is centered around the life of a eleven year old girl, Melody Brooks, struggling with an extreme case of cerebral palsy. Melody is stuck in a wheelchair and can not talk but, she has a photographic memory. Melody first describes how her school started “inclusion classes” for the disabled students where they go to classes with average students. Melody realized that she knew a lot of the information the teacher would describe and she so badly wanted to answer questions but she was unable do

My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

Air drag also depends on the air density: the lower the density, the less air drag. Less drag gives a better chance of the batter hitting a homerun. The conditions that lower the air density are higher temperature, higher humidity, and higher elevation. As temperature is increased, the air molecules become more spread out and lower the air density. A higher humidity is better because water vapor is less dense than dry air.

Research Report Should Kids Head the Ball In Soccer. Kids heading the ball is very dangerous because many kids can get concussions they can also get concussions from hitting each others heads that is most common when players try to head the ball. Kids under the age of 11 or 10 shouldn’t be able to header the ball. Heading the soccer ball.

My question looks at how gravity, and the weight and size of different balls affects how long it takes to hit the ground. The balls I choose was the American football, golf ball, baseball, and tennis ball. As learned in this experiment, weight and size affect how fast the ball drop because gravity will cause the heavy ball to drop faster. This means that the heavier ball should fall faster, while the lighter ball should fall slower. I choose this topic because I want to know if ball sizes influence how fast the ball will hit the ground.

The side of the ball traveling with the airflow pulls the air along its surface using friction, while the other side traveling against the ball slows the air down. This can lead to a downward force on the air and, in relation to Newton’s law of motion, results in an upward force on the ball. The side of the ball with the faster moving air will have a lower pressure than the side of the ball moving against the airflow. This relationship causes the ball to move towards the area of lower pressure, resulting in the curve of the ball while spinning in the air (McKeithen,

Many parents, including mine, are becoming weary of their children playing soccer. This sport, just like football, is gaining this reputation because of the risk of concussions from heading the ball. Also, like football, there is equipment being developed to make this sport safer. Instead of helmets, it is headbands to reduce the impact from the ball. In Delaney’s study on the effect of headgear in soccer, he showed showed how this protective equipment in soccer does a lot to help prevent against concussions (Delaney) There were a couple different results that he found in this study showing this.

Softball is a sport I have been playing since I was eight. Running the bases is something I have enjoyed about playing the game. With my experience with softball, it led me to question which size ball would travel the farthest. Thus, my experiment question is “Which size ball would travel the longest distance when thrown?”.

In this paper I will be pointing out the physics concepts of friction, gravity, and drag as they relate to the sport of Soccer. I will also tell you how you will profit from it, if you are a Soccer player The first physics concept that I will examine is friction. Friction is always happening in Soccer. For example, when the ball hits the grass it causes friction, and that friction causes the ball to drag, each time that it bounces on the field, it causes friction and that friction leads to the ball being unable to continue rolling forever.

Physics Applied to Soccer Soccer. The most popular game in the world, and yet the most beautiful. This sport is known for its skill and its way of bringing people together. Though what most don’t know is that a great amount of physics can be applied to the game of futbol. From Newton’s Laws of Motion, to things such as friction and inertia, there is so much to learn from this sport.
